Prepare for Repository Merge

  1. Perform the following tasks. For information on performing these tasks, see the chapter in Siebel Database Upgrade Guide that describes how to perform the Siebel Repository merge:

    • Migrate Siebel Repository objects to the standard user interface (UI).

    • Configure Siebel Repository objects to inherit upgrade behavior.

  2. About Backing Up the New Customer Repository or Database Schema.

  3. Execute the REORG utility on tables that receive a large number of inserts during the repository import process. For a list of the tables that must be reorganized at this point, see About Reorganizing Tables Before the Repository Merge.

  4. Run database statistics on the Siebel repository tables. For further information on running database statistics, see Generating RUNSTATS Jobs. Running statistics on the Siebel repository tables improves merge performance.

    If upgrading from Siebel CRM versions 7. 7 or 7.8.x, run statistics specifically on the S_SYM_STR and SYM_STR_INT tables. If you are upgrading from a pre-7.7 Siebel CRM release, the S_SYM_STR and SYM_STR_INT tables are not populated until the merge is completed so you do not have to run statistics on them at this point.
